Airedale Chemical EDTA is also known in the industry as Tetrasodium salt and is primarily used to dissolve limescale.


Cleaning Chemicals & Detergents

Reduction of water hardness in laundry applications and the dissolution of scale in boilers both rely on EDTA and related complexants to bind Ca2+, Mg2+ as well as other metal ions.

Energy & Waste Management

EDTA is a slime dispersant, and has been found to be highly effective in reducing bacterial growth during implantation of intraocular lenses EDTA is used extensively in the analysis of blood

Textile Chemicals & Dyes

Prevents metal ion impurities from modifying colours of dyed products.


Used in the manufacturing of shampoos and other personal care products – EDTA salts are used as a sequestering agent to improve their stability in air.

In the pulp and paper industry EDTA inhibits the ability of metal ions. Mainly used to sequester metal ions in aqueous solution. Used in the separation of the lanthanide metals by ion-exchange chromatography.

Food & Beverage – EDTA is used for chelation and is also added to food products for utilization as a stabilizer as well as a preservative because it inhibits oxidation and rancidity.


Its usefulness arises because of its role as a hexadentate ligand and chelating agent. As a solution EDTA is a yellow colourless liquid and as a solid is a colourless powder
